[Name] DIRNAME

[Description] This creates a text box where the user may enter the absolute path
              for a folder. If the button is pressed, a folder picker dialog
              appears and the user is able to pick a folder from there. 
              
              DIRNAME is meant to be used in destination context (as opposed to DIRNAME_SRC).
